10.1.4.CALIBRATION FREQUENCY

To ensure accurate measurements of the CO concentrations, calibrate the analyzer at the time of installation, and recalibrate it:

No later than three months after the most recent calibration or performance audit which indicate the analyzer’s calibration to be acceptable.

When there is an interruption of more than a few days in analyzer operation.

When any repairs have taken place which might affect its calibration.

After a physical relocation of the analyzer.

When any other indication (including excessive zero or span drift) of possible significant inaccuracy of the analyzer exists.

Following any of the activities listed above, the zero and span should be checked to determine if a calibration is necessary.

10.1.5.LEVEL 1 CALIBRATIONS VERSUS LEVEL 2 CHECKS

Essential to quality assurance are scheduled checks for verifying the operational status of the monitoring system. The operator should visit the site at least once each week. It is recommended Level 1 zero and span check conducted on the analyzer every two weeks. Level 2 zero and span checks should be conducted at a frequency desired by the user. Definitions of these terms are given in Error! Reference source not found..

To provide for documentation and accountability of activities, a checklist should be compiled and then filled out by the field operator as each activity is completed.
